GAR-LIFTING DEVICE.

Application. filed April 23, 1925. Serial No. 25,201.

To all whom 2 2, may concern:

Be it known that I, ALLAN O. CARPENTER, a citizen of the United States,and a resident of Corning, county of Steuben, State of New York, haveinvented a certain Car-Lift ng Device, of which the following is aspecification accompanied by drawings.

This invention relates tolifting devices for cars, such as railway cars,adapted to run 011 a track, in order that the car may be shifted fromthe track on transverse lifting wheels running on transverse rails. I

The objects of the invention are to enable the car to be readily andquickly lifted and shifted on transverse wheels by simple de- "viceswhich are at the same time cheap and rugged in construction.

Another object of the invention is to permit the car to be carrieddirectly upon the transverse wheel yokes or supports when shifted, sothat'the weight of the car is not borne by the'transverse wheels whileat rest on the transverse rails.

The invention is shown in one of its preferred forms in the accompanyingdrawings, in which a Figure l'is a diagrammatic side elevation of thelifting device applied to a portable compressor car adapted to run onarailway track and intended to be used for furnishing compressed air forthe operation of tie tamper tools;

Figure 2 is an enlarged detail top plan view partly in transversesection of the lifting device on the line 2-2 of Figure l;

Flgure 3 is an end elevation partly broken away of the car shown inFigure 1 illustrating the lifting devices with the lifting wheelslocatedupon a transverse rail in the act of lifting the tie tamper car;

Figure 4 is a view similar to Figure 3 showing the tie tamper carshifted transversely from the main track and resting on the liftingwheels;

Figure 5 is an enlarged detail vertical sectional viewof one of thelifting devices on the line 55 of Figure 2 looking in the direction ofthe arrows and illustrating the device in the same position indicated inFigure t with the lifting device locked;

Figure 6 is a view similar to Figure 5 showing the manner in which theweight of the railway car is permitted to rest directly upon the liftingwheel yokes which are lodevice comprises a similar view showing the thecompressor E furnishing compressed air to the storage tank or reservoirF. The weight of the car and of the operating machinery carried therebyis considerable, so that the lifting devices must be capable ofwithstanding the strain necessarily imposed in lifting the car upontransverse wheels G and shifting it along the transverse rails H.

The tie tamper car is preferably provided with four lifting devices, oneon each corner is illustrated in the drawings and these lifting devicesare preferably in the form of attachments which may be secured to thecar frame A in "any suitable or convenient manner. As shown in thedrawings, each lifting yoke bracket J having an attaching member K and aforked supporting member L. The attaching member K of the yoke bracketis adapted to be secured to the car frame A as by means of bolts 0 and Pand extends downwardly from the frame. In the fork L of this yokebracket is pivoted a wheel yoke Q having a forked portion R and alifting member S, which lifting member is preferably in the form of asocket adapted to receive the end of an ordinary lining bar T which isalways avail able when tie tan'ipering operations are in progress,although any suitable bar or lever will suffice for rocking the wheelyokes on their pivot pins U. The lifting wheel G is pivoted to theforked portion of the wheel yoke by means of the pin V.

A suitable locking device in the form of a latch W is provided forlocking the lifting device with the lifting wheel G in raised positionas indicated in Figures 1 and 7 when the railway car is travelling onthe main track rail C. This latch is also adapted to lock the liftingwheel G in located position as indicated in Figures 3 and 5 TOINGERSOLL-RAND COM- wheels located in raised position The car is whenthe railway car is being shifted transversely along the transverse railsH; The latch IV is slidable vertically in the groove or guideway Xformed in the attaching member of theyoke bracket and is provided with aslot Y through which one of the bolts P passes to limit the movement ofthe latch. The lower end Z of the latch cooperates with the stop aformedon the wheel yoke for locking the wheel yoke and lifting wheel inlocated posit-ion as indicated in Figure 5, and also cooperates with theweb I) on the wheel yoke forming a stop in order to lock the wheel yokeand lifting wheel in raised position as indicated in Figures 1 and 7.The latch may be raised and lowered by means of the hooked portion a inorder to permit the running of the wheel yoke on its pivot, andv whenthe yoke is in the desired position the latch is dropped to lock theparts.

In Figure 6, the tie tamper car has been rolled upon the transverserails and then while the car is to remainat rest, the wheel yokes havebeen rocked to raise the lifting wheels and the bearing portions (Z andthe wheel yokes have been permitted to lie directly upon the transverserails II so that the lifting wheels G are out of contact with said railsand the entire weight of the tie tamper is carried by the wheel yokesdirectly upon the transverse rails. The latch WV has been lowered andthus locks the parts in position.

I claim:

I. In a railway car, the combination with the car frame and trackwheels,of transverse yoke brackets attached to the car frame, transverse wheelyokes pivoted to said yoke brackets, lifting wheels carried by saidwheel yokes, means for rocking said transverse wheel yokes', and meansfor locking said wheel yokes either in raised or lowered posit-ion ofthe Wheels.

2. In a railway car, the combination with the car frame and trackwheels, of transverse yoke brackets attached to the car frame,transverse wheel yokes pivoted to said yoke brackets, and having barsockets and lower bearing members adapted to bear upon transverse rails,and lifting wheels carried by said wheel yokes, whereby the railway carmay be wheeled transversely from the track along transverse rails andthen lowered and supported at rest directly on the wheel yokes.

3. In a railway car, the combination with the car frame and trackwheels, of transverse yoke brackets attached to the car frame,transverse wheel yokes pivoted to said yoke brackets, and having barsockets and lower bearing members adapted to bear upon transverse rails,and lifting Wheels carried by said wheel yokes, whereby the railway carmay be wheeled transversely from the track along transverse rails andthen lowered and supported at rest directly on the wheel yokes, andmeans for locking said wheel yokes either in raised or lowered positionof the wheels.

i. In a railway car, a car lifting device comprising a yoke brackethaving an attaching member and a forked supporting member, a wheel yokepivoted to the said supporting member and having a forked portion and alifting member, a lifting wheel carried by said forked portion, and alatch adjustable on the attaching member of the yoke bracket for lockingthe wheel yoke in raised or lowered position of the wheels.

In testimony whereof I have signed this specification.

ALLAN O. CARPENTER.
